Description

This is a continuation-in-part application of our copending application Ser. No. 538,507, filed on Jan. 6, 1975, (now U.S. Pat. No. 4,084,059, issued Apr. 11, 1978) which is a division of Ser. No. 299,741, filed on Oct. 24, 1972 (now patent 3,870,748), which is in turn a continuation-in-part application of Ser. No. 877,497, filed Nov. 17, 1969, now abandoned.
The present invention relates to 2-hydroxy-1,1,2,3,3-pentahydro-perfluoroalkyl derivatives, and their production and use. More particularly, it relates to new and useful 2-hydroxy-1,1,2,3,3-pentahydro-perfluoroalkyl derivatives, to compositions containing the same suitable for treating fibrous materials to render them oleophobic and anti-soiling, and to fabrics and fibers which have been sized or coated with the same so as to have been rendered oleophobic and anti-soiling.
The new compounds of the present invention are representable by the general formula: ##STR4## wherein Q is a hydrogen atom, --CH2 CH(OH)CH2 Rf or a hydrocarbon residue having a valence corresponding to m which may contain one or more of --O--, --COO--, --NH--, --N═ and ##STR5## in the chain, R is a hydrogen atom, a hydrocarbon residue or --CH2 CH(OH)CH2 Rf and m is an integer of not less than 1, Rf being a perfluoroalkyl group, an ω-hydroperfluoroalkyl group or an ω-chloro-perfluoroalkyl group having 4 to 20 carbon atoms.
Hitherto, there have been proposed various methods for imparting anti-soiling property to fibrous materials. For instance, fabrics made of hydrophobic synthetic fibers or fabrics processed with a hydrophobic synthetic resin are treated with a solution or suspension of a hydrophilic substance such as polymers having acrylic acid as the unit constituent, polyethylene glycol derivatives and carboxymethyl cellulose so that the soils attached to the fabrics are apt to be eliminated and laundering. This method, however, fails to prevent soil attachment itself. Further, for instance , fabrics are treated with a solution or dispersion of polymers of C8 F17 SO2 N(C2 H5)CH2 CH2 OOCH═CH2 or C8 H17 CH2 CH2 OOCC(CH3)═CH2 or of chromic acid compounds having a polyfluoroalkyl group such as C7 F15 COOCr2 (OH)Cl4 to impart oil-repellent property to them whereby the attachment of oily and aqueous stains is prevented. However, it is quite difficult to remove the once attached stains by laundering, and stained parts increase during laundering by adsorption and preservation of soils contained in washings on the surface of the fabrics.
It has now been found that the perfluoroalkyl compounds [I] can impart excellent oil-repellent and anti-soiling properties to fibrous materials treated therewith. Aqueous and oily soils are difficult to attach on the treated fibrous materials and, even if attached, can be readily and completely eliminated by laundering in ordinary manners. Thus, the perfluoroalkyl compounds [I] are useful as oil-repellent agents and anti-soiling agents. In addition, they are useful as plasticizers and also as intermediates for fluorine-containing polyurethanes.
The perfluoroalkyl compounds [I] can be produced by reacting a perfluoroalkylpropylene oxide of the formula: ##STR6## wherein Rf is as defined above with a reagent of the formula:
Q'(NHR').sub.m                                             [III]
wherein Q' is a hydrogen atom or a hydrocarbon residue having a valence corresponding to m which may contain one or more of --O--, --COO--, --NH-- and --N═ in the chain, R' is a hydrogen atom or a hydrocarbon residue and m is as defined above.
Examples of the hydrocarbon residue represented by Q' in the formula [III] are alkyl, aralkyl, cycloalkyl, aryl, alkylaryl, alkenyl, etc. These groups may optionally have an oxyalkylene chain therein. Examples of the hydrocarbon residue represented by R' include lower alkyl such as methyl, ethyl or propyl.
The expoxide [II] may be prepared, for instance, by adding radically a perfluoroalkyl iodide of the formula: RfI wherein Rf is as defined above to allyl alcohol and treating the resultant alcohol of the formula: RfCH2 CHICH2 OH wherein Rf is as defined above with an alkali hydroxide (e.g. sodium hydroxide, potassium hydroxide) in water to eliminate hydrogen iodide therefrom. Examples of the epoxide [II] are as follows: ##STR7##
As the reagent [III], there may be employed primary amines, secondary amines or ammonia.
Examples of the primary amine and the secondary amine are ethylamine, diethylamine, propylenediamine, hexamethylenediamine, pentaethylenehexamine, melamine, octadecylamine, hexamethylenetetramine, aniline, diethylenetriamine, triethylenetetramine, cyclohexylamine, benzylamine, benzylaniline and an amine containing a polyethylene oxide chain of the formula: R"HNR'O(CH2 CH2 O)p R'NHR" wherein R" is a hydrogen atom or an alkyl group and R' and n are each as defined above (e.g. H2 N(CH2)3 O(CH2 CH2 O)n --(CH2)3 NH2, C2 H5 NH(CH2)3 O(CH2 CH2 O)n (CH2)3 NHC2 H5, CH3 NH--(CH2)3 O(CH2 CH2 O)n (CH2)3 NHCH3, ##STR8##
The reaction between the epoxide [II] and the primary amine [III] proceeds as follows: ##STR9## Thus, the reaction of the epoxide [II] with the primary amine [IIIa] in equimolar amounts affords the secondary amine [Ia] and, when the epoxide [II] is employed in two molar amount to one molar amount of the primary amine [IIIa], there is obtained the tertiary amine [Ia']. The reaction between the epoxide [II] and the secondary amine [IIIb] is represented by the formulae: ##STR10## In place of the primary amine [IIIa] or the secondary amine [IIIb], there may be used ammonia [IIIc], which is reacted with the epoxide [II] as follows: ##STR11##
All the above reactions are usually effected by treating the epoxide [II] with the primary amine [IIIa], the secondary amine [IIIb] or ammonia [IIIc] in a slightly excess amount at a temperature of from 30° to 150° C., preferably from 80° to 100° C. The use of a solvent is not always needed. If employed, the use of an inert organic solvent such as fluoroalkanes is recommended for controlling the elevation of temperature caused by generation of heat. In general, the presence of water in the reaction system is unfavorable, and its amount should be suppressed not more than 10% by weight. The reactions can be promoted by the use of a tertiary amine (e.g. triethylamine). The reactions are normally completed in 30 minutes to 10 hours to give the perfluoroalkyl compound [Ia]-[Ic"] in nearly quantitative yields. The thus obtained perfluoroalkyl compound [Ia ]-[Ic"] may be further converted into its acid addition salt by treatment of the former with an organic or inorganic acid usually at a temperature from room temperature to 100° C., if desired, in an inert organic solvent such as fluoroalkanes. This conversion is advantageously carried out immediately after completion of the reaction between the epoxide [II] and the primary amine [IIIa], the secondary amine [IIIb] or ammonia [IIIc], i.e. without the isolation of the produced perfluoroalkyl compound [Ia]-[Ic"] from the reaction mixture. The perfluoroalkyl compound [Ia]-[Ic"] itself is a liquid or solid which is insoluble in water, whereas most of its acid addition salts are soluble in water. Both are utilizable for the object of this invention.
The produced perfluoroalkyl compound [Ia]-[Ic"] is fallen in one of the following formulae: ##STR12## wherein R1 and R2 are each a hydrogen atom or a hydrocarbon group bearing or not one or more substituents. Specific examples are as follows:

As stated above, the perfluoroalkyl compounds [I] (including the acid addition salts) have oleophobic and anti-soiling properties. Based on such properties, they are used for treatment of fibrous materials.
On treating fibrous materials with the perfluoroalkyl compound [I] (including the acid addition salt), the active ingredient is dissolved or dispersed in a suitable solvent to make a concentration of 0.05 to 5% by weight, the fibrous materials are immersed therein and the wet materials are dried in atmosphere or while heating at 80° to 150° C. for 30 seconds to 10 minutes.
As the solvent, the use of an organic solvent having a boiling point from 30° to 150° C., particularly from 35° to 100° C., is preferred. Specific examples of such organic solvent are fluoroalkanes (e.g. trichlorotrifluoroethane, dichlorotetrafluoroethane), ketones (e.g. acetone, methyl ethyl ketone), esters (e.g. ethyl acetate), fluorine-containing cyclic compounds (e.g. benzotrifluoride), etc. For dilution of these solvents, there may be also used benzene, petroleum ether, xylene or the like.
From the economical viewpont, it is advantageous to make up an aqueous dispersion. Thus, the active ingredient is dispersed in water in the presence of an appropriate emulsifier by conventional operations. Examples of the emulsifier are anionic surfactants (e.g. sodium dodecylbenzenesulfonate, C7 F15 COONa), non-ionic surfactants (e.g. polyoxyethylenealkyl phenyl ether, polyoxyethylene amyl ester, sorbitan fatty acid ester), cationic surfactants (e.g. quaternary ammonium salts), etc.
The textile fabrics treated with the anti-soiling treatments of this invention are quite excellent in repellency to stains, stain-removing actions, prevention of soil redeposition during laundering and durability to laundering and show very favorable appearance.
The perfluoroalkyl compound [I] (including the acid addition salt) is also used for the separation of water and oil (e.g. kerosene, sesame oil, heavy oil, machine oil, watch oil, refrigerator oil, hexane, heptane, octane, cyclohexane) from their mixture. For instance, porous materials such as paper, woven fabric, non-woven fabric and asbestos are treated with the active ingredient dissolved or dispersed in water or organic solvents, if necessary, by the aid of surfactants so that the porous materials are imparted oil-repellency and allows only the passing of water therethrough.
The perfluoroalkyl compound [I] (including the acid addition salt) may be also employed in combination with any water-phobic agent. In such case, the materials treated with them are imparted both oil-repellency and water-repellency. Examples of the water-phobic agent are the polymers of the fluorine-containing vinylcarboxylic esters of the formula: RfCH2 CH(OH)CH2 OOCCR3 ═CH2 where R3 is a hydrogen atom or a methyl group. The vinylcarboxylic esters may be produced, for instance, by reacting the epoxide of the formula: ##STR15## or the diol of the formula: RfCH2 CH(OH)CH2 OH with acrylic acid or methacrylic acid. The ratio by weight of the perfluoroalkyl compound [I] and the vinylcarboxylic ester is 9:1-1:9, favorably 5:1-1:5. On treatment, these active ingredients are employed in the form of solution or dispersion in water or organic solvents, if necessary, by the aid of surfactants.
In addition to the above uses, the perfluoroalkyl compound [I] (including the acid addition salt) may be used as plasticizers or intermediates for the synthesis of polyurethanes. For instance, the amine of the formula: [RfCH2 CH(OH)CH2 NH]2 A wherein A is a hydrocarbon group bearing or not one or more substituents or its mixture with an active hydrogen-containing material such as ethyleneglycol adipate, propyleneglycol adipate, condensates of ω-hydroxyhexanoate or glycerol adipate is polymerized with a diisocyanate of the formula: OCNA'NCO wherein A' is a hydrocarbon group (e.g. 2,4- or 2,6-tolylenediisocyanate, 3,3'-bitolylene-4,4'-diisocyanate, diphenylmethane-4,4'-diisocyanate, 3,3'-dimethyldiphenylmethane-4,4'-diisocyanate, metaphenylenediisocyanate, triphenylmethanetriisocyanate, 2,4-tolylenediisocyanate dimer, hexamethylenediisocyanate, naphthylene-1,5-diisocyanate). The polymerization is effected at a temperature from room temperature to 150° C., preferably in the presence of a small amount of a catalytic substance (e.g. ethylenediamine, triethylamine, triethylenediamine, dimethylethanolamine, bis(diethylethanolamine) adipate, N,N-dimethylcyclohexylamine, dibutyl tin laurate, dibutyl tin di(2-ethylhexoate), stannous 2-ethylcaproate, stannous oleate). The ratio of the perfluoroalkyl compound [I] and the diisocyanate to be used may be appropriately decided on the kind of the polyurethane to be required. The thus obtained polyurethane has oleophobic and anti-soiling properties and possesses a wide variety of uses, e.g. the use as coating materials, the use as additives to painting, etc.
Practical and presently preferred embodiments of the invention are illustratively shown in the following Examples. In these Examples, parts and percent are by weight unless otherwise indicated. Further, various properties such as water-repellency, oil-repellency, stain-removability and anti-soil redeposition in the following examples are determined by the methods as described below:
1. Water-repellency
Measurement is effected according to A.A.T.C.C. Standard Test Method 22-1952.
2. Oil-repellency
Measurement is effected according to A.A.T.C.C. Standard Test Method 118-1966Y.
3. Stain removability
A test cloth is put on a blotting paper extended evenly, and 5 drops of liquid paraffin in admixture with purple dye "Waxoline Purple AS" (manufactured by I.C.I., England) are added dropwise onto one place of the test cloth, which is covered with a polyethylene film. The test cloth is pressed by 2.27 kg of poise for a minute, which is removed. The excess of the liquid paraffin is wiped off with a cotton cloth. The test cloth is allowed to stand for 12 hours and laundered.
Laundering is effected with a drum side-rolling automatic washing machine (manufactured by Sakata Kiko Co., Ltd.). To cloths (300 g) including the test cloth, there are added water (15 L) warmed at 45° C. and a conventional cleaning material (e.g. "Kao Big" (made by Kao Soap Co., Ltd.)) (38 g). The resultant mixture is laundered for 10 minutes and washed with water for 2 minutes three times. Liquid paraffin-removing degrees are judged by the decolored degree of the purple color. Standard of the decolorization is as follows: same color as that of unlaundered cloth: 1.0; completely decolored case: 5.0; grades between them are judged respectively.
4. Anti-Soil redeposition
Soil redeposition bath (150 ml) having the composition as defined in the following table is adjusted, stirred at 50° C. well, and 6 sheets of test cloth (6×6 cm) and 15 steel balls are added to the bath. Soiling of the test cloth is effected by turning Launder-O-Meter at 50° C. for 20 minutes. The soiled cloth is washed with water for 10 minutes and air-dried.
The reflectance of the test cloth is measured by using a photometer and the rate of soil redeposition is calculated by the following equation: ##EQU1##
